There materials can be made into the base layer of sticker labels; glassine is one of them. It is a very thin and smooth paper that is air and water resistant. It is translucent unless dyes are added to color it or make it opaque. It is manufactured by super calendaring: after pressing and drying, the paper web is passed through a stack of alternating steel and fiber-covered rolls called a super calendar at the end of the paper machine such that the paper fibers flatten facing in the same direction. Glassine is very popular in the decoration. Glassine is also recommended for protecting the surface of stored acrylic paintings. Glassine is used as a base paper for making greaseproof paper. Philatelists use glassine envelopes to store stamps, and stamp hinges are sometimes made of glassine sticker labels. Amateur insect collectors use glassine envelopes to store specimens temporarily in the field before they are mounted in a collection. Entomologists collecting for research may likewise use glassine envelopes to store whole specimens in the field. However, if the research involves DNA or other tissue analysis the relevant parts of the body will be placed immediately in a preservative such as ethanol. With the development of technology, more and more advance materials will be applied to make labels. When this is done for Lepidoptera the wings will often be separated and stored indefinitely in glassine envelopes in case the wing patterning or venation is required later to confirm the identity of a specimen. Glassine sticker labels are used to carry pharmacy reformulated drugs and prohibited drugs such as cocaine and heroin. In the mid-20th century, potato chips were packaged in glassine bags. Glassine packages firecrackers. Glassine is used for its transparent qualities to fold origami tessellations. Glassine is an outer covering on cardboard tubes, particularly those used in model rocketry, for water protection. |
